Product classification
HS code for Producer gas: 2705.00
Gases, coal, water, producer and similar gases (excluding petroleum and other gaseous hydrocarbons).
Classification of producer gas under HS 2705.00
Producer gas is classified under HS code 2705.00. This heading includes coal gas, water gas, producer gas, and similar gases. These are manufactured gases typically obtained by the carbonization or gasification of coal, coke, or other carbonaceous materials, including biomass. Unlike natural gas or petroleum gases, which are classified under heading 2711, producer gas is a manufactured product consisting primarily of a mixture of carbon monoxide, hydrogen, and nitrogen. The classification is determined by the chemical composition and the industrial process used to generate the gas, as outlined in the Explanatory Notes to Chapter 27. Producer gas is created by passing air (sometimes with steam) through a thick layer of incandescent fuel; the oxygen in the air is converted to carbon monoxide, resulting in a combustible gas with a relatively low calorific value. This code is essential for distinguishing between naturally occurring fuel gases and those produced through industrial gasification. The HS system places these under Chapter 27 because they are mineral fuels or products of their distillation, even though they are in a gaseous state and manufactured rather than extracted.
- Covers
- Producer gas from coal gasification
- Water gas (hydrogen and carbon monoxide)
- Wood gas (from biomass gasifiers)
- Coal gas (town gas)
- Blast furnace gas
- Also under 2705.00
- Industrial syngas production (e.g., from coal gasification plants)
- steel mill blast furnace gas utilization
- coke oven gas recovery systems
Codes often confused with 2705.00
Common mistake. Producer gas is most commonly confused with HS code 2711, which covers petroleum gases and other gaseous hydrocarbons like methane, propane, and natural gas. It may also be confused with HS code 2804, which covers pure chemical gases like hydrogen or nitrogen. Producer gas is a mixture, not a pure chemical element, and thus belongs in Chapter 27.
Top exporters and importers of HS 270500 (the code used for producer gas), 2025
In 2025, the largest exporter of HS 270500 (the code used for producer gas) in UN Comtrade data was the Netherlands, with 42% of world exports; the largest importer in UN Comtrade data was Italy, with 83% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about producer gas
What is the HS code for Producer gas?
The HS code for Producer gas is 270500 (Gases; coal, water, producer and similar gases (excluding petroleum and other gaseous hydrocarbons)). The HS code for producer gas, coal gas, and water gas is 2705.00.
How do I classify Producer gas for customs?
Producer gas is classified under HS code 270500 — Gases; coal, water, producer and similar gases (excluding petroleum and other gaseous hydrocarbons). This is a 6-digit subheading level code.
Is biogas classified under this code?
Biogas, which consists primarily of methane, is generally classified under HS code 2711.29 as an 'other' gas in the petroleum gas heading, rather than under 2705.00.
Which countries are the top exporters of producer gas (HS 270500)?
In 2025, the top exporters of HS 270500 (the code used for producer gas) in UN Comtrade data were the Netherlands ($2.5M, 42% of world exports), Estonia ($1.4M) and Singapore ($728K). World exports came to about $5.9M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of producer gas (HS 270500)?
In 2025, the top importers of HS 270500 (the code used for producer gas) in UN Comtrade data were Italy ($12M, 83% of world imports), the Netherlands ($422K) and France ($394K).
